Article Synopsis
- The study investigates the changes in gray matter (GM) volume in the insula, a brain region linked to addiction, comparing severe alcohol use disorder (sAUD) and severe cocaine use disorder (sCUD).
- Researchers analyzed 12 subregions of the insula using a sample of 50 sAUD patients, 61 sCUD patients, and 36 healthy controls, finding overall lower insula volume in both disorders, particularly in the anterior long gyrus (ALG).
- The results highlight both shared and distinct patterns of insula volume deficits between sAUD and sCUD, suggesting that while the insula is important in substance use disorders, each disorder may have unique characteristics that could inform treatment approaches.
Article Synopsis
- Alcohol use disorder is a chronic condition that leads to harmful impacts on a person’s overall health, which can also result in Korsakoff's syndrome, a serious complication marked by significant memory problems.
- This study aimed to analyze how long-term alcohol consumption affects brain connectivity, specifically in areas known as the fronto-cerebellar and Papez circuits, and to identify unique connectivity issues in patients with Korsakoff's syndrome.
- Researchers conducted neuropsychological assessments and resting-state functional MRI on both healthy individuals and those with alcohol use disorder to discover reduced connectivity efficiency in the brain's circuits and to explore the relationship between brain function and cognitive abilities in the context of these conditions.
Researchers and clinicians have long used meaningful intransitive (i.e., not tool-related; MFI) gestures to assess apraxia-a complex and frequent motor-cognitive disorder.

However, the anatomical counterpart of these functional modifications in sAUD patients with and without neurological complications remains largely unexplored, especially using state-of-the-art parcellation tools. We thus compared the grey matter volume of insular subregions (form anterior to posterior: anterior inferior cortex, anterior short gyrus, middle short gyrus, posterior short gyrus, anterior long gyrus, posterior long gyrus) in 50 recently detoxified patients with sAUD, 19 patients with Korsakoff's syndrome (KS) and 36 healthy controls (HC).

This phenomenon is known as the global precedence effect (GPE), which is demonstrated by (1) a global advantage, resulting in faster response times for global features than local features and (2) interference from global distractors during the identification of local targets, but not vice versa. This GPE is essential for adapting visual processing in everyday life (e.
